The point (8,-4) lies on a circle. What is the length of the radius of this circle if the center is located at (5,-7)
Kamila [148]
Notice the picture, the radius is just the distance from the
center to a point on the circle, thus

\bf \textit{distance between 2 points}\\ \quad \\\\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%  (a,b)
&({{5}}\quad ,&{{ -7}})\quad 
%  (c,d)
&({{ 8}}\quad ,&{{ -4}})
\end{array}\qquad 
%  distance value
\\\\\\
\begin{array}{llll}
d = &\sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}\\
&\qquad \uparrow \\
&radius
\end{array}

\bf \begin{array}{llll}
d = &\sqrt{({{ 8}}-{{ 5}})^2 + ({{ -4}}-{{(-7)}})^2}\\
&\qquad \uparrow \\
&radius
\end{array}
\\\\\\
d=\sqrt{(3)^2+(-4+7)^2}\implies d=\sqrt{3^2+3^2}\implies d=\sqrt{18}
\\\\\\
d=\sqrt{9\cdot 2}\implies d=\sqrt{3^2\cdot 2}\implies d=3\sqrt{2}

  • <em>Answer:</em>

<em>the missing term is 5</em>

<em>Hi there ! </em>

<em>12x² - 75 = </em>

<em>= 3(4x² - 25)</em>

<em><u>use formula</u></em><em> a² - b² = (a - b)(a + b)</em>

<em>= 3(2x - 5)(2x + 5)</em>

<em>= 3(2x + 5)(2x - 5) </em>

<em>the missing term is 5</em>

<em>Good luck !</em>
